Verifique o seu hardware
Inspecionar os cabos e as ligações
First, ensure that all cables and connections are secure. Loose or damaged cables are a common cause of ‘No Internet Connection’ issues. Begin by inspecting the Ethernet cable connected to your router and modem. Ensure both ends are firmly plugged in. If you are using a powerline adapter, check its connections as well.
Next, examine the condition of your cables. Look for any visible signs of wear and tear, such as fraying or bending. Replacing a damaged cable can often resolve connectivity problems. Additionally, if you are using a wireless connection, ensure that your router’s antennas are properly attached and positioned upright.
Ao inspecionar e fixar cuidadosamente os seus cabos e ligações, pode eliminar esta causa potencial de interrupção da Internet e avançar para outros passos de resolução de problemas, se necessário. Este simples passo pode poupar-lhe muito tempo e aborrecimentos.
Reiniciar o router e o modem
Restarting your router and modem is a simple yet effective troubleshooting step when facing a ‘No Internet Connection’ issue. To do this, first, unplug the power cords from both your router and modem. Wait for about 30 seconds to allow the devices to fully power down. This brief pause helps to clear any temporary glitches or errors that might be affecting your connection.
Em seguida, volte a ligar o modem e aguarde que este seja totalmente reiniciado. Este processo demora normalmente alguns minutos, uma vez que o modem restabelece a ligação com o seu fornecedor de serviços Internet (ISP). Quando as luzes do modem indicarem uma ligação estável, ligue o router. Mais uma vez, aguarde que o router conclua o processo de arranque.
Depois de ambos os dispositivos serem reiniciados, verifique a sua ligação à Internet. Esta ação simples resolve frequentemente muitos problemas de conetividade comuns, actualizando as definições e ligações de rede.
Verificar definições de rede
Verificar as definições de Wi-Fi
If you’re encountering a ‘No Internet Connection’ message, your Wi-Fi settings might be the culprit. Start by ensuring that your Wi-Fi is turned on. On most devices, you can find this option in the settings menu under ‘Network’ or ‘Wi-Fi’. If the Wi-Fi is off, toggle it on and see if your device connects to the network.
Em seguida, verifique se está ligado à rede Wi-Fi correcta. Por vezes, os dispositivos ligam-se automaticamente a redes abertas ou a redes com um nome semelhante. Confirme que está ligado à sua rede doméstica ou do escritório, verificando o nome da rede (SSID) nas definições de Wi-Fi.
If you continue to experience issues, forget the network and reconnect. To do this, select your network from the list of available networks, choose ‘Forget’, and then reconnect by entering the password again. This can resolve issues related to incorrect or outdated network settings.
Verificando cuidadosamente e ajustando as definições de Wi-Fi, pode frequentemente restaurar a ligação à Internet e resolver quaisquer problemas relacionados.
Confirmar a configuração da rede
Ensuring your network configuration is correct is crucial when dealing with a ‘No Internet Connection’ issue. Start by accessing your device’s network settings. On a Windows PC, you can do this by going to ‘Control Panel’ > ‘Network and Internet’ > ‘Network and Sharing Centre’. On a Mac, navigate to ‘System Preferences’ > ‘Network’.
Check the status of your network connection. If it’s marked as ‘Public’, consider changing it to ‘Private’ for improved connectivity and security. Ensure that your IP e as definições de DNS são definidas para serem obtidas automaticamente, exceto se utilizar um endereço IP estático.
For advanced users, manually configuring the DNS settings to use a reliable DNS server, such as Google’s (8.8.8.8 and 8.8.4.4), can sometimes resolve connectivity issues. Additionally, verify that no proxy settings are interfering with your connection.
Ao confirmar e ajustar a configuração da rede, pode eliminar potenciais erros de configuração que possam estar a causar problemas de conetividade. Este passo é vital para garantir uma ligação à Internet estável e fiável.
Diagnosticar problemas de software
Atualizar controladores de rede
Outdated or corrupted network drivers can often be the cause of a ‘No Internet Connection’ issue. To update your network drivers, first, access the Device Manager on your computer. On a Windows PC, you can do this by right-clicking the Start menu and selecting ‘Device Manager’. On a Mac, updating drivers typically involves updating the entire sistema operativo through ‘System Preferences’ > ‘Software Update’.
In Device Manager, expand the ‘Network adapters’ section. Right-click on your network adapter and select ‘Update driver’. Choose the option to search automatically for updated driver software. If an update is available, the system will download and install it.
If automatic updates do not resolve the issue, you may need to visit the manufacturer’s website to download the latest drivers manually. This ensures that you have the most recent and compatible version for your network adapter.
Ao manter os controladores de rede actualizados, pode evitar muitos problemas de conetividade e manter uma ligação à Internet estável.
Desativar a Firewall temporariamente
Sometimes, an overzealous firewall can block your internet access, leading to a ‘No Internet Connection’ message. To determine if your firewall is the cause, you can disable it temporarily. On a Windows PC, navigate to ‘Control Panel’ > ‘System and Security’ > ‘Windows Defender Firewall’. Click on ‘Turn Windows Defender Firewall on or off’ and select ‘Turn off Windows Defender Firewall’. On a Mac, go to ‘System Preferences’ > ‘Security & Privacy’ > ‘Firewall’ and turn it off.
After disabling the firewall, check if your internet connection is restored. If it is, the firewall settings might need adjustment to allow internet traffic. Remember to turn the firewall back on after your test to maintain your system’s security.
If disabling the firewall resolves the issue, consider adding your network or specific applications to the firewall’s allowed list. This way, you can maintain your security settings without compromising your internet connection.
Gerindo cuidadosamente as definições da firewall, é possível equilibrar eficazmente a segurança e a conetividade.
Contactar o fornecedor de serviços Internet
Verificar a interrupção do serviço
If you’re still seeing a ‘No Internet Connection’ message after trying various troubleshooting steps, there may be a service outage in your area. Start by checking your ISP’s website or social media channels for any announcements regarding outages. Many ISPs provide real-time updates on service status.
Além disso, pode utilizar sítios Web de acompanhamento de falhas de energia, como o DownDetector, para ver se outros utilizadores na sua área estão a comunicar problemas semelhantes. Estas plataformas oferecem mapas e relatórios de utilizadores que podem ajudá-lo a identificar se o problema é generalizado.
If you can’t find any information online, call your ISP’s customer support. They can confirm if there is an outage and provide an estimated time for resolution. Keep your account information handy to expedite the process.
Verifying a service outage can save you time and prevent unnecessary troubleshooting. If an outage is confirmed, all you can do is wait for your ISP to restore service. Ensuring you’re informed can help you manage expectations and plan accordingly.
Procurar assistência profissional
If you’ve exhausted all troubleshooting steps and still rosto a ‘No Internet Connection’ issue, it might be time to seek professional assistance. Contact your ISP’s technical support for help. Their technicians can remotely diagnose issues and may identify problems that weren’t obvious during your checks.
When contacting support, provide details of the steps you’ve already taken. This information can help the technician pinpoint the issue more quickly. Be ready to follow their instructions, which may include additional troubleshooting or resetting your equipment.
Em alguns casos, o ISP poderá ter de enviar um técnico ao local. Este pode inspecionar a configuração física, testar as linhas e efetuar as reparações necessárias.
A assistência profissional garante que os problemas complexos são tratados por especialistas, poupando-lhe tempo e frustração. Também proporciona paz de espírito, sabendo que a sua ligação à Internet está a ser restabelecida por pessoal qualificado.
